`IMPROVEMENT IN I TURB-INE WATER-WHEELS.

The` Schedule referred, to invthes'e Letters Patent and making part ofthe sama.

To whom it may concern Be it known that I, MCKENDRE A. Bnooks, of LaForte, in the county of La Porte and State of Indiana, have invented anew and useful Improvement in 'lurbiue \Vater-\Vheels; and I do declarethat the following is a true and accurate description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked t-hereon and being a part of this specification, inwhiclw- Figurelis an elevation showing 'the `case and wheel 'in section.4

Figure 2 is a section on the line a: fc, iig. 1.

Like letters indicate like parts in each ligure.

The nature of this invention rela-tes to an improvement in that class ofwater-wheels which is provided with sliding-ring gate interposed betweenthe buckets of the wheeland stationary chutes, and in the method ofoperating the saine. p

The invention consists in giving such a gate a downward movement inopening, whereby the 'water is directed. to the tops ofthe buckets inasolid column when less than a full gate is given; also in the novel andpeculiar construction of the inechanisru for'operating such gates, asmore fully hereinafter set forth.

In the drawing- Arepresents the case of my wheel, between the upper andlower portions of which are arranged the chutes B, rising irom the topand eenterof thc case A, and rigidly secured thereto in a hollowstandard,

C?, provided with a screw-thread, D.

E is a Vertical shaft passing through the standard C and case A.

rlhis shaft is stepped upon an adjustable bearing, F, in thefoundation-frame G, upon which the case A is rigidly secured.

E is the hub of the wheel, rigidly secured to the shaft E near its lowerend, within the case A.

Radiating from this hub are buckets I.

J is a spider, the hub of which encireies the standard F.

Within this hub is placed a rotating collar, K.

L is a stud projecting from the hub ofthe spider J, through which isjournaled the rod M. rlhe lower end of this rod is V provided with apinion, N, which meshes with the teeth c of the collar K. lhe upper endof the rod M passes through the guide O, and is provided with a properhand-wheel, I.

Projecting downward from the ontervends of the arnis of the spider J arethe rods It, passing through the case A, as shown in iig. l.

S is a ring-gate, interposed between the chutes B and the buckets of thewheel. 'Io the flange b of this .gate are rigidly secured the lower endsof the rods It.

Ihe operation ot' this device is as follows:

y turning the hand-wheel I) to the left it will be seen that the collarK will turn down the screw I) of the standard, also carrying with it thespider J; and, by reason of thc connection between the spider and thegate by the rods It, the gate will also be moved downward, thus openingmore orless communication between the chutes and the buckets whenpartizilly Y closed.

rlhe action of the gate iirtliis` .manner causes the water admittedthrough the chutes to strike the upper portion of the buckets of thewheel, acting upon the whole face of the saine before it can bedischarged. By this means the full force of thelwater is obtained,

a portion cf-which would be lost if admitted at the iled.
